Since wireless communication can be interrupted by a number
of factors, you must test your alarms weekly to ensure proper
communication between alarms.
If your Kidde smoke alarms enter smoke alarm mode, first check
for a fire. If a fire does not exist and the test buttons have not
been activated on any of the units, it is likely that you are receiving
interference from a similar system nearby. In this case, repeat the
above steps and select a different DIP switch pattern. Be sure to
remove the batteries before changing the switch positions.
The interconnect system should not exceed the NFPA interconnect
limit of 12 smoke alarms.

To help identify the date to replace the alarm, a space has been
designated on the product label affixed to the back of the alarm.
Write the “replace by date” (ten years from initial power up) in
permanent marker on the label (see Alarm Replacement section for
additional information).
